Incompetent, jack booted thugs.
Not even capable of identifying themselves properly and then charge her with a crime for protecting herself as any sensible woman would do.
In the 60s in Orlando, one night I had (what turned out to be) an unmarked cop try to pull me over with no lights, just started waving at me and pulling up next to me. Hell if I was going to stop at 1 am with no other cars around. Then he turned on the lights and after I pulled over gave me a lot of crap about not stopping at once. Prick.
Not incompetence.
Sadism.
These officers clearly *enjoyed* attacking a group of young women.
Those who *enjoy* terrorizing the innocent will soon not be able to get their jollies from terror alone.
So long as people chalk up such incidents to incompetence, police departments will continue to *promise* to train their officers better, and incidents like this will continue and escalate.
